The Power Integrations SIC1181KQ is a highly integrated, single-channel gate driver specifically designed for SiC MOSFETs in automotive applications. It utilizes FluxLink™ technology for reinforced galvanic isolation and offers ±8 A peak gate output current, enabling it to drive devices with nominal currents up to 600/800 A. This device features advanced active clamping for overvoltage limitation and ultrafast short-circuit detection for enhanced safety.
The SIC1181KQ operates within a temperature range of -40 °C to +125 °C and supports switching frequencies up to 150 kHz. It includes undervoltage lock-out (UVLO) protection for both primary and secondary sides, ensuring safe operation even in harsh conditions. The gate driver is housed in an eSOP package with 9.5 mm creepage and clearance, and CTI 600.
Key features include rail-to-rail stabilized output voltage, high common-mode transient immunity (35kV/µs typical), and propagation delay jitter of ±5 ns. The device is AEC-Q100 qualified for automotive grade 1 and meets VDE V 0884-17 pending and UL 1577 recognized standards. It is also RoHS compliant and halogen-free.
Applications for the SIC1181KQ include electric vehicle (BEV) traction drives, hybrid electric vehicle (PHEV) traction drives, and electric vehicle on-board and off-board chargers. Its robust design and safety features make it suitable for demanding power electronic systems.
